#1 Never assume the previous owner did anything correctly. You should verify the jetting in the carb, even if it is new. A lot of these carbs come from China. And they're not all jetted the same.
#2 what air cleaner are you running?
#3 please take pics of the hose routing going to the carb. I'm really interested in where the hose with the "T" is going.
#4 Check the hose coming off the valve cover for obstructions (crank case vent)
#5 Wouldn't be a bad idea to check the valves for adjustment while you're inspecting the vent hose in the valve cover.
There are good videos on U tube showing how to check/adjust your valves for the gy6 150.
This should help a bit too. http://www.familygokarts.com/manuals...ice_manual.pdf
